  • Patent number: 6720791
    Abstract: An LCD panel testing method. The method comprises forming jump lines in a predetermined region on the substrate between the signal lines via mask design when forming TFT LCD arrays, and thus forming a plurality of signal-line groups each with two signal lines coupled by the jump lines. Thereupon, an array tester sequentially tests two pixels corresponding to the signal lines in the signal groups. If one of the feedback signals from the signal groups does not meet a predetermined standard, it is determined that one or both pixels in the signal group are defective. The defective pixel or pixels are then identified using an electronic microscope to test two pixels at the same time. In this way, the number of probe pins and tests performed is halved. The probe pin size is also thus less restrictive due to larger probe pin intervals. Consequently, yield is greatly increased.

  • Patent number: 6717984
    Abstract: A method of analyzing a sample waveform in the time domain. Firstly, a periodic wave, such as a sinusoidal wave, is inputted into a waveform processing module for obtaining a sample waveform. Next, a detection of a number of peaks of the sample waveform is performed. A determination is then made as to whether the period of the sample waveform is obtainable from the peaks of the sample waveform. If not obtainable, it indicates the waveform processing module is malfunctioning. If obtainable, a determination is then made as to whether the period of the sample waveform is equal to the predicted period. According to this determination, it indicates whether the waveform processing module is functioning.

  • Patent number: 6718548
    Abstract: A method for embedding an operating system and application program into a memory apparatus. The operating system includes a boot file and a run control (RC) program and the method includes the steps as follows. First, source codes of the operating system are processed for obtaining a crunch file of the operating system by applying a crunch technique. The crunch file of the operating system is then compiled, resulting in an executable file of the operating system which is then compressed into a system compression file. Next, eliminating unnecessary comments and settings from source codes of the application program, a compact version of the application program is obtained. Following that, a program storage file is mounted as a mount point through a virtual node technique. Next, the compact version of the application program is copied to the mount point. The program storage file is then compressed into a program compression file.
